The present invention relates to valves, adapted particularly for use incompressors, and has `for an object certain improvements in theconstruction of these valves which are 5 known as of the feather type.

Y:so

' the In the construction of the` present used feather compressor valve,a plurality of plates or strips are employed which are o f a. iieXiblecharacter and which under' pressure are bowed or sprung away from theirrespective seats with the result that there is consid- Verable wear,Jfriction andgeneration of heat Another object of the present inventionis Y to provide improved means for vseparating the strips at theiropposite ends and holding them in true alignment'withtheir respectiveseats, this means also serving as wearingv surfaces adapted lto take upwear between the strips and the valve so that themeans may be renewedfrom time to time and thus save the expense of providing new valves orvalve parts.

The invention also aims at the provision of a feather compressor valveembodying the above characteristics and which maintains the generalconfiguration and structure ofV valves of this type so that they may bereadily substituted thereforand be manufactured with the desiredcapacity for the pressure medium without any appreciable change in thedimensions of the ports and Vother parts of the valve. e

1 With the foregoing and other objects in view, the invention will'bemore fully described hereinafter, and will'be more particu-Y larly:pointed out in the'y claims appended hereto. Y A' Y 'r Y In thedrawings, wherein like symbols retoward and from their fer to like orcorresponding partstthroughout th-efseveral viewsLi` f 'f1 Y Figure 1 isa face view of oneside ofthe valve, showing theiblades, wearkeys and reain'ote ports in dotted lines.

` Figure 7 .is a detail perspective view `of one ofthe blades or strips,and

`ljfigure 8 isa `detail perspective view of one of thewearkeys'employed. j Referring n'ow to 'the drawings, 10 designatesthe'valve body ,which is in the form of a plate of circular orfotherdesiredconfiguration; and'whicli` is provided with Va plurality ofsubstantially paralle'lf slots1'1 throughV which fluid under pressure isadapted to pass. 'I he (inner face of the valve' body V10` is'relatively lat so as to provideyalve seats around the slots'1'1,andthesaid flatinnerface of the `body valve is adapted to receive thereagainst-a pluralityv ofstrips or blades 12 providing 8 the movable elementsofthe valve. 'y

" There isastripjor'bladeu12- for each slot 11 as shown clearly indotted lines in Figure 1, and the strips or blades 'are of sufficientwidth land lengthfto' overlap tlie'inarginal edges of the slots so Vasto effectively close the slots and preventpassage ofthe fluid underpressure `in one directionthrough the valveV l For the purpose ofholding the strips or blades in vposition againstvthe inner fflatffsideof the valvebody 10,-afi/*alve guard 13 is em ployed.A The valve guard13"'mayfbe inthe i form of aj companion platec'orresponding to the"dimensions *andi 'configuration of fthe valve'bod 10 and which isadapted to be secured'inl ace contact therewith by means of bolts 14 orthe like; The valve guard 13 is provided with a. plurality of slots 15extending therethrough, which are disposed substantially inparallelrelation to one another and which are also disposed in stag ered or Y Yoifsetrelation to thekslots 11 in t e valve body 10.

`The strips or blades 12 are spaced apart yso that fluid may pass yaboutthe edges thereof and thus be carried from the slots 11 into and throughthe slots 15 when the strips'or blades 12 are in openposition as shownin Figures 2 and 3.

'v Y. As may be best seen from Figures-V and 6, the valve guard isprovided at opposite sides of its marginal edge portion and atv itsinner face with recessesorpockets 16 of asuitable width to freelyreceive therein :the opposite lends of the strips or blades 12 andwhichv are of a depth corresponding` `to theV amplitude of vibratorymovement of the strips or blades 12 .during their opening vandclosingoperations. v Y Y These pockets 16 are open against the 1nnerflat side of the valve body 10,'and are Y thus closed by `the, valvebodyy when the two valve guard is providedv with shallow grooves' plates10 and 13 aresecured together. It lwill also be noted that the innerface of the or recesses 17 which correspond in width and depth to thewidth and depth of thepockets 16 `and form continuations thereof, and

which are also disposed lin parallel relation to one another forreceiving the blades or strips 12 and permitting the'coinplete o eningand closing movements thereof Wit out flexing or bending the strips orblades. The

strips lor blades 12 may thus be'forme'dof a Vcheaper material thanislusuallythe case wherein the blades of the present construction ofpressure valve must have 'inherent yrieysiliencyr and vmust, be ofa veryhigh grade ymaterial to withstand the continuous flexingv vorbendingaction. .1

For the p-urposeof holdingthe blades or strips 12 in'spaced apartrelation and to take up Wear between-the lateral edges thereofandithevalve guard` orV blade 13, Wear keys or blocks 18, shown linFigurefS, are employed and the same may be of segmental or otherconfiguration presenting an inner flat -face 19 for engagement againstthe inner dat face ofthe valve body 10. vThe valve guard l is prm'ided`at opposite sides of eachl pocket 16 with s.- recess or depression 20,with its walls shaped jto thefconguration of the lower portion of thekeys 18 so as to snugly receive the-same and to thnslbvear against theoppositel edgesy of the adjacent strips 12,.'

As's'hown, each block 18. hasaajrou'nded lower side and when its .flatupper side 19 is Vengaged bythe valve body 10, theP key vl 18 is lturned or rocked intoA proper alignment withl `lengths simultaneouslyand from the adjacent face of the valvegbody tc close andxopen the-slotsthereof, and' rethe valve guard and the valve body. As shown inFigures1, 3 and 4 particularly, these keys 18 are of a width equalsubstantially to the space between the lateral edges of` the strips orblades 12 so that the strips or upon the `valve body 10, the valveguard13V and thebladesor strips112. f

A further feature of thisV construction is i that the strips yor blades12 when moved to an open position provide arelative clearance which isof equal-width from end tolend' of` the blade and thus'thevalve has`greater capacity for passage of fluid under pressure in the open.position. Y g

`It is obvious that variouschanges and modifications may be made in theVdetails of construction and design of the above specifically describedembodiment yof this invention Without departing from th'espiritthereof,such.clianges and modifications'being restricted only by thescope of the-followingl claims. n
